When running with podman and xpra (x11docker --podman --xpra --desktop --size 1400x900 x11docker/mate) x11docker builds a command line that includes --cap-drop ALL which causes the container startup to fail:

Error: container_linux.go:346: starting container process caused "apply caps: operation not permitted": OCI runtime permission denied error

When adding --cap-default to the startup the container launches successfully. (x11docker --podman --xpra --cap-default --desktop --size 1400x900 x11docker/mate)

Thank you for reporting this!
I cannot reproduce the issue here.

What is your podman version? Here it is podman version 2.0.4.
What is your host system, maybe fedora? Here it is Debian bullseye.

For reference, the x11docker podman ticket is: mviereck/x11docker#255
